The gate control theory of pain says that pain impulses traveling through the lateral spinothalamic tract can be suppressed by increased activity of the

A) anterior spinothalamic tract.
B) tertiary neurons.
C) extrapyramidal tracts.
D) dorsal column/medial lemniscal system.
E) spinocerebellar tracts.

Gate Control Theory

A theory positing that pain signals encounter nerve gates at the spinal cord level that can block or allow the sensation of pain to travel to the brain.

Lateral Spinothalamic Tract

A pathway in the spinal cord that transmits pain and temperature sensations to the brain.

Anterior Spinothalamic Tract

The anterior spinothalamic tract is a sensory pathway of the spinal cord that carries information about light touch and pressure to the brain.
